Stream APIs and codecs move to first-class typed sources

This release promotes the EVM and Solana stream layers around typed data sources and request builders, with matching codec and typegen changes for ABI-heavy workflows. It also adds API-key support across Gateway settings and hardens several runtime paths, including RPC retries, archive credentials, hot block recovery, and Substrate call parsing.
